A low cost monolithic accelerometer; product/technology update

Abstract
Described is a complete monolithic accelerometer, which combines a surface micromachined polysilicon sensor with BiMOS interface circuitry. As much as possible, the device exploits existing high volume wafer fabrication technology. Ultimately, this scheme should make acceleration sensing a commodity function, with signal span accuracy approaching 5%. The circuit architecture is reviewed and recent characterization results reported.
